JOHN F. BUSTIN, OF PASADENA, CALIFORNIA.

LAWN-SPRINKLER.

Specification of Letters Patent.

Patented Jan. 26, 1915.

Application filed July 5, 1912. Serial No. 707,917.

To all whom it may concern Be it known that 1, JOHN F. BUSTIN, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented a new and useful Lawn-Sprinkler, of which the following is a specification.

My invention relates to a water sprinkler of the type used for sprinkling lawns and plants, and consists of a sprinkler head provided with a series of intercommunicating chambers formed therein, each of which chambers is provided with outlet means which direct the water sprayed therefrom to predetermined portions of the area sprayed, and means whereby water is introduced into one chamber from a suitable water supply under pressure, a portion of which water passes successively from one chamber to another under gradually diminishing pressure, so that the water sprayed from each successive chamber is thrown a lesser distance from the sprinkler head than the water sprayed from the preceding chambers.

The main objects of my invention are to produce a sprinkler of the class described of simple form and construction, and having high efiiciency in operation.

Referring to the drawings, which are for illustrative purposes only: Figure 1 is a front elevation of asprinkler embodying a form of my invention. Fig. 2 is avertical, sectional view on line w 0a Fig. 1. Fig. 8 is a sectional, plan view on line as -x Fig. 1. Fig. 4 is a side elevation of one of the cups forming part of the sprinkler head. Fig. 5 is a diagrammatic view of a plot of ground sprayed by the form of sprinkler shown in Figs. 1 to 4 inclusive, and also showing the position of the sprinkler with relation thereto.

in the form of device shown in Figs. 1 to 5 inclusive, the sprinkler consists of a head 1 having a base 2 provided at one side with an interiorly threaded hose connection 3 which communicates with a passage 4 extending inwardly and upwardly through the base 2. The sprinkler is supported upon the ground by means of two oppositely extending arms 6, the inner ends 7 of which are threaded and extend into a threaded opening 8 in the-base 2. The hose connection 3 may be connected to any suitable flexible hose 9 of well known form to supply the sprinkler with water, which hose 9, together with the arms 6, supports the sprinkler in the vertical position shown in Fig. 1.

The upper end 10 of the base 2 is provided with a circular seat 11 adapted to receive the lowermost of a series of inverted cups 12. Each cup 12 consists of a flat central portion or bottom 13 terminating in a circular flange 14 having a portion thereof pressed outwardly to form a circular rib 15, which ribs 15 are provided in their upper portion 16 with a plurality of outlet openings or perforations 17. The upper portions 16 of the ribs 15 are formed with a longer slope than the lower portions 18, the slope of the portions 16 being so arranged that the water sprayed through the perforations 17 is thrown upwardly and outwardly from the sprinkler in such a manner that the maximum length of throw of water from the sprinkler is attained.

The cups 12 are arranged one above another, as clearly shown in Figs. 1 and 2, the edge 20 of each cup being of large enough diameter to fit down over the next lower cup until the edge 20 engages the rib 15 thereon. As many cups 12 may be arranged as just described, one above another, as may be essential for the particular purpose for which the sprinkler may be designed. The uppermost cup 12 has placed thereon an inverted bowl or cap 24 having perforations 25. The edge 26 of the bowl 24 fits over the uppermost cup 12 above the rib 15 thereon.

The cups 12 are held together by means of a stud 27 which extends through an open- 'ing 28 in the bowl 24, thence through a central opening 30 in each cup 12 and through a threaded opening 31 in the base 2. The stud 27 is provided at its upper end with a nut 32 which engages the bowl 24 on the top thereof and the lower end of the stud 27 is engaged by a lock nut 33 below the base 2 by means of which the bowl 24, cups 12 and.

tudinal groove 35 in the stud 27 anda lug 36 on each cup 12, which lugs 36 extend into the groove 35 in the stud.

The cups 12, when secured together in the manner heretofore described, comprise the sprinkler head 1, the circular flanges 14 of the cups constituting the sides of the head, and the bottom 13 of the cups constituting division walls which divide the head into a plurality of chambers 40, one above another, which chambers 40 are in open communication with each other by means of perforations 41 which extend through the bottom 13 of the cups 12. The perforations 41 in the cups are graduated in size, the lowermost cup having the largest opening and the perforations 11 in the cups thereabove being reduced in area as may be necessary to obtain the required restriction or reduction of the head of water in the various chambers 40.

The form of sprinkler shown in Figs. 1 to 5 inclusive, just described, operates as follows: Water under pressure is introduced into the sprinkler through a hose 9 attached to the "hose coupling 3 of the sprinkler head. The hose coupling-is in open communication with the sprinkler head by passage 4 which delivers water under pressure into the lowermost chamber 40 of the sprinkler head. A portion of the water in the lowermost chamber 40 passes out through perforations 17 in the lowermost cup 12, which perforations are placed in the cup so as to deliver water to the farthest point from the sprinkler head in the plot desired to be sprinkled. The perforations in the sprinkler head, in the form shown, are so arranged as to sprinkle a rectangular area, shown in Fig. 5, the sprinkler being placed centrally-on one of the long sides of the plot to be sprinkled, as indicated, in which case the perforations 17in the lowermost cup of the sprinkler head deliver the water upon lines indicated at 12. A portion of the water in the lowermost chamber 40 passes through the perforations 4:1 in the bottom 13 of the lowermost cup into the second chamber, a

portion of the water in the second chamber being sprayed outwardly through perforations 17 in the second cup, which perforations are arranged to deliver water to the next farthest ortion of the plot to be sprinkled, as indicated by lines 43in Fig. 5 of the drawings, the length of the throw of water through the perforations in the second cup being less than the throw of water from the lowest cup by reason of the reduction of pressure of the water in the second cup. The water passes on upwardly through the successive cups and is -sprayed from the perforations 17 therein successively to distances gradually diminishing from the sprinkler head until the water which passes through the perforations 11 in the uppermost cup into the bowl 24 is delivered through the perforations 25 therein to the portion of the plot to be sprinkled immediately around the sprinkler head.

In the form of sprinkler head above described, it is to be noted that the perfora tions in the series of cups forming the sprinkler head are all placed within the half of the circumference of the sprinkler head farthest away from the'hose connection, so that the sprinkler head may be approached from the hose side of the sprinkler head, while the sprinkler is in operation, and carried to any portion of the ground desired to be sprinkled without the person so doing getting wet either from the spray of water from the sprinkler or walking upon the wet ground.
